KPA100 no PA Key Out

[Martin]

Elecrafters,
a friend is trying to connect his K2/100 to his external amp. I own a
K2/10 only , so have no expirience with it.

He performed measurements and found the PA Key Out on the rear panel of
the KPA100 will not go low on transmit.
What could be the cause?
Thanks.

Martin,

It could be a solder failure, a failure of Q12, an open R1, or a bad
output from firmware U1 pin 16.

Sorry for the bandwidth, we found it ourselves. The 8r Hold parameter
was set to 0.01 .
